---+ !SimDB/REST 
!SimDB is based on a data model.
Data models are supposed to be represented in UML and be accompanied by an XML schema.
In !SimDB we propose the following usage for this schema
   * Defines valid !SimDB/XML documents.
   * Such documents can be retrieved upon a simple GET request (format to be decided) for single (or multiple?), identified !SimDB/Resource(-s).
   * Such documents MAY be used if a !SimDB instance allows upload/insertion of !SimDB/Resource-s.

---+ TODO
Issue to be discussed:
   * Only concrete (i.e. non-abstract) root entity classes mapped to root elements
   * use of predefined base.xsd
   * each package mapped to own XML doc with own targetnamespace
   * identifiers structured 
      * database id (a long)
      * ivoIdentifier
      * xml ID (for references internal to doc)
      * ?publisherDID?
   * references mapped to element containing just an identifier
   * ...


---+ Comment: Priorities

In order to keep up the progress on !SimDB becoming a recommendation, the !ReST interface is secondary to finalizing the data model and mapping it onto a TAP service. I think we should set this topic aside until we have some !SimDB services implemented. If users start to query the databases, they may begin asking for a common mechanism to add metadata about their simulations. This would be the point to finalize the !ReST interface.
